Hi Licenio. The tablet you have is running on the Android operating system and I very much doubt it would work with Windows 8. Besides, Win8 would use up all your internal memory and leave no room for any applications to run on it so you can forget that idea. If you want a Windows 8 tablet you should purchase one with it already installed. You should instead just leave it running with the latest version of Android that should already be on your tablet, Version 4.1.1.
